Abstract

The invention discloses an extrahigh-voltage inverter noise reduction device with automatic pressure relief and high-temperature fusing functions. The extrahigh-voltage inverter noise reduction devicecomprises fixing parts, hot melting and noise reduction plate parts, hot melting and noise reduction plate and hot melting support combination parts, an explosion venting part and a hot melting anti-falling net. Fixed cross beams and firewalls are arranged on the two sides of the upper portion of inverters correspondingly. The fixing parts are set up between the fixed cross beams and the firewalls. Moving cross beams are erected above the inverters. The hot melting and noise reduction plate parts are arranged between the moving cross beams. The explosion venting part is erected on the periphery of a sleeve ascending base of the inverters. The hot melting anti-falling net is arranged below the hot melting and noise reduction plate parts, the hot melting and noise reduction plate and hot melting support combination parts and the explosion venting part. The extrahigh-voltage inverter noise reduction device with the automatic pressure relief and high-temperature fusing functions has the advantages of being capable of automatically relieving pressure and timely melting-off under the effect of inverter explosion pressure and fire high temperature and good in safety performance.

Description

technical field [0001] The invention relates to the field of disaster prevention and reduction in electric power systems, in particular to an ultra-high voltage converter noise reduction device with functions of automatic pressure relief and high-temperature fusing. Background technique [0002] The converter transformer is one of the most important equipment in the converter station, and it is also the main source of noise in the station. The Box-in noise reduction device of the converter transformer is equivalent to reducing the sound source power from the source, which plays an important role in meeting the noise standard of the converter station. However, while the Box-in noise reduction device meets the noise reduction requirements, it also creates new problems. For example, when a fire occurs in the converter transformer, the closed Box-in noise reduction device hinders the effective function of the fire extinguishing medium during the external fire extinguishing proce...
